* A fire extinguisher is required at all performances which use any fire demonstrations. Officers should know how to operate the fire extinguisher, and have it in an accessible spot throughout the show. | |||
* Fire safe gloves must be available for all fire demonstrations. Safety glasses and goggles are required to be worn for all fire demonstrations. A small blast shield is required for any fire demonstrations that sit on a table. A large blast shield is required for all other fire demonstrations if the audience will be closer than 15 feet to the demonstration. | |||
* If the demonstration involves a combustible liquid, the container must be kept sealed and at least six feet away from the ignition source. The container should only be open when measuring out the liquid needed, and should otherwise always be kept closed. Combustible liquids are volatile, meaning they readily dissipate into the air around them. This is what makes them hazardous, for the fumes from combustible liquids are more flammable/explosive than the liquid itself. | |||
* If the demonstration involves a dry combustible powder or material, keep the ignition source at least six feet away at all times. If it is a powder, it should be kept in a sealed container until it is being measured out. When it is poured out, place it into a dish or bowl with high walls, to prevent moving air from carrying any of it. If it is a solid material to be burned, such as wood, set it up appropriately and ignite it once you are ready. | |||
* If the demonstration involves a combustible gas, such as the Methanol Cannon, keep the gas in an airtight container at all times, at least 6 feet away from the ignition source. Only open the gas container when it will be ignited within seconds. | |||
* If the demonstration involves a constant flame, such as the Flame Tube or Candy Conflagration, keep the audience at least six feet away if you have a blast shield. Otherwise, they must be 15 feet away. Presenters must keep their hands away from the flames at all times. The audience should never be allowed to get close to the flames. | |||
* If the demonstration involves a sudden hot flame, such as the Methanol Cannon or KMnO4 and Glycerin, The demonstration must be performed behind a blast shield. | |||
* Most of these demonstrations give off some form of smoke. Be aware of any smoke detectors or fire alarms in the presentation space, and confirm with the contact before the show that you will be allowed to have smoke. See below under the Flying Particle Safety section for more information on smoke and similar micro-particles. --> | |||

- This page lists all safety precautions and requirements for demonstrations. Please read over carefully before performing any demonstrations.
Fire Demonstration Safety
Cryogenic Demonstration Safety
Loud Demonstration Safety
Dry Chemical Demonstration Safety
Liquid Chemical Demonstration Safety
Flying Particle Demonstration Safety
Under Construction Some of our demonstrations release particles or debris during the performance. Please take the following precautions if you are performing a demonstration which releases particles:
- Use a blast shield, if possible. It will help protect the audience from any debris.
- Have a designated "Blast Radius" for the demonstration. If you have a blast shield, the minimum radius is six feet. If you do not, the minimum radius is fifteen feet.
- All presenters and volunteers must wear safety glasses or safety goggles when the demonstration is being performed. Presenters not involved in the demonstration should stay outside of the blast radius.
- If the demonstration fires particles in one direction, it should be aimed away from the audience and other demonstrations.
If a demonstration gives off smoke or any similar micro-particles, then please use the following safety precautions:
- Only perform a demonstration which gives off smoke or similar micro-particles in a well ventilated area
- Notify the contact for the event prior to the event that the demonstration gives off smoke. They may need to move your presentation to a new room, or ask for a different demonstration to replace it.
- Be aware of any smoke alarms in the room, if any, and avoid using the demonstration near one.
- Do not let anyone from the audience to come close to a demonstration that is still giving off smoke.

Other Demonstration Hazards and Safety Precautions
Radioactivity Demonstration
- This demonstration utilizes a Geiger Counter, which needs to be carefully taken care of. Remove the batteries from the Geiger Counter when it is no longer in use to preserve battery life. It is a sensitive piece of equipment, so never drop it or you may disrupt the equipment inside. If after use you notice that the batteries are low, be sure to plug the device in when you return to the planetarium, and allow it to charge overnight. Do not leave it plugged in for more than 24 hours.
- This demonstration uses radioactive objects. Be careful not to let small children put any pieces of the plate in their mouths. Do not let anyone keep a piece of the plate. The plate gives off Beta-decay and Alpha-decay, so it should be kept in the plastic container until the presentation. The pieces are safe to hold and examine, but be sure to have all pieces returned to you before the end of the demonstration. The Uranium ore sample gives off Beta-decay and Alpha-decay as well, and is safe to handle. Make sure to have all radiation sources returned to you and placed into the container before the end of the performance.
- All Science Theatre Officers who will be using this demonstration should go through the EHS Radiation Safety Refresher Training. Officers and volunteers are not required to go through this training, but officers are strongly encouraged to do so, and are required to instruct volunteers on safe handling of radioactive samples, the Geiger Counter, and proper presentation of this demonstration.
